The status of the “ENGINE START STOP” switch remains stored in the
vehicle memory. When the vehicle battery is discharged, the vehicle
returns to the status before the battery was discharged after disconnect-
ing and reconnecting the battery. When the battery needs to be discon-
nected, turn the “ENGINE START STOP” switch off before disconnecting
the battery. If the “ENGINE START STOP” switch status before the bat-
tery discharge is unknown, pay due attention to the vehicle when the bat-
tery is reconnected.
Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
CAUTION
Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery.
Make sure the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any part other than the intended termi-
nal.
Do not allow the jumper cables to come into contact with the “+” and “-” ter-
minals.
Do not allow open flame or use matches, cigarette lighters or smoke near
the battery.
Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery.
When working with the battery, always wear safety glasses and take care
not to allow any battery fluids (acid) to come into contact with skin, clothing
or the vehicle body.
Do not lean over the battery.
